asp.net webcontrols : Problem programmatically creating tabstrip webcontrol

I hope I'm getting the right group this time.

I am trying to programmatically build a tabstrip (creating a template
class for my site that contains a tabstrip in the header). I'm using
the tabstrip from "Microsoft.web.ui.webcontrol" (iewebcontrols).

I have a form (as htmlform) to which I am adding controls and html
(via literalcontrol) and I try to add the tabstrip as follows:

'declare and initialize as appropriate:
Dim tsTopNav As Microsoft.Web.UI.WebControls.TabStrip = New
Microsoft.Web.UI.WebControls.TabStrip

Dim tiHome As Microsoft.Web.UI.WebControls.TabItem

'set tabstrip properties
tsTopNav.ID = "tsTopNav"
tsTopNav.AutoPostBack = True
tsTopNav.SepDefaultImageUrl = "/gfx/spacer.gif"
tsTopNav.TabDefaultStyle.Add("background-color:", "#e6e6e6")
tsTopNav.TabDefaultStyle.Add("font-family", "verdana")
etc...

'set up tabitem
tiHome.Text = "Home"

'add tabitem to tabstrip
tsTopNav.Items.Add(tiHome)

and I get
"Object Reference not set to and instance of an object" in the line
where tiHome.text = "Home" happens.

Somehow tiHome is not properly being set up.

Any ideas?

got it... the rather obvious (thought I had tried it and then finally
went back and tried it again out of frustration)

Dim tHome As Microsoft.Web.UI.WebControls.Tab = New
Microsoft.Web.UI.WebControls.Tab

tstopnav.items.add(tHome)
